We have been wondering what’s the secret behind the iPhone 11 Pro Max that has the best battery life of any iPhone so far, and the speculated 3500mAh, or even the earlier 3650mAh rumor couldn’t explain the whole picture.
Granted, the new OLED display generation and more efficient A13 chipset add to the record real-life battery endurance of the phone, but they still can’t be adding 5 more hours to the battery life of the phone as Apple claims in the specs sheet.
